/*
 * Bob Denny 28-Aug-82  Remove reference to FILE *lexin to
 * 						eliminate dependency on standard I/O library. Only
 * 						lexgetc() used it, and it's there now.
 *						Add EOF	definition for standalone uses.
 *						Corrected comment for llnxtmax.
 *
 * Scott Guthery 20-Nov-83	Adapt for IBM PC & DeSmet C.  Removed
 *							equivalence of yylval and lexval since
 *							a multi-typed parser wants yylval to be
 *							typed to be the union of the types (YYSTYPE).
